Is Andromeda 2 million light years away?

The Andromeda Galaxy (IPA: /ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy with the diameter of about 46.56 kiloparsecs (152,000 light-years) approximately 765 kpc (2.5 million light-years) from Earth and the nearest large galaxy to the Milky Way.

Is the Andromeda Galaxy located over 2 million light years away?

The Andromeda galaxy (Messier 31), which is located 2.5 million light-years away, is the Milky Way's nearest large galactic neighbor.

Is the Andromeda Galaxy 2500000 light years away from the Milky Way?

Located 2.5 million light-years away, the Andromeda is our largest nearby galactic neighbor. The galaxy's entire disk spans about 260,000 light-years, which means that a light beam would take 260,000 years to travel from one end of the galaxy to the other.

Are we seeing Andromeda 2.5 million years ago?

So 2.5 million years is about 79,000,000,000,000 seconds - so Andromeda is now about 8,700,000,000,000,000 kilometers closer than it was when the light we see was emitted by it. That's about 900 light years. But Andromeda is not a small object! It's about 200,000 light years across.

How do we know that the Andromeda Galaxy is 2.5 million light years away?

In 1764 famed comet observer Charles Messier cataloged the Andromeda Galaxy as his listed object known as M31! Here is an image of the Andromeda Galaxy as viewed from Earth. With the advent of modern telescopes and science, the Andromeda Galaxy is now known to be some 2.5 million light years from us.

The Andromeda Galaxy | 2.5 Million Light-years From Earth | ☄️

What will Andromeda look like in 4 billion years?

According to simulations, the remnant will look like a giant elliptical galaxy, which is a blob-like galaxy without discernible spiral arms or an internal structure. Andromeda galaxy contains about one trillion stars and the Milky Way contains about 300 billion.

How many years is 1 light year?

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

How can we see something 35 billion light years away?

It's because the space between any two points — like us and the object we're observing — expands with time. The farthest object we've ever seen has had its light travel towards us for 13.4 billion years; we're seeing it as it was just 407 million years after the Big Bang, or 3% of the Universe's present age.

Do light years go back in time?

Measuring in light-years also allows astronomers to determine how far back in time they are viewing. Because light takes time to travel to our eyes, everything we view in the night sky has already happened. In other words, when you observe something 1 light-year away, you see it as it appeared exactly one year ago.

How many years will Andromeda hit us?

The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (113 km) per second. With this in mind, our merger will occur five billion years from now.

Will the Milky Way survive Andromeda?

Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us. Our galaxy's spiral arms will disappear, and so will our supermassive black hole.

Which is older Andromeda or Milky Way?

Astronomers believe the Andromeda Galaxy is 10.01 billion years old. This makes it younger than our Milky Way Galaxy which is believed to be 13.2 billion years old.

What is the biggest galaxy?

A spectacular new photo has been released showing the record-holder for largest galaxy in the universe. NGC 6872, also known as the Condor Galaxy, stretches 522,000 light years from tip to tip.

Is the Milky Way galaxy is about 100000 light years wide?

The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.

What will the Andromeda Galaxy look like 7 billion years in the future?

Fourth Row, Left: In 5.1 billion years the cores of the Milky Way and Andromeda appear as a pair of bright lobes. Fourth Row, Right: In 7 billion years the merged galaxies form a huge elliptical galaxy, its bright core dominating the nighttime sky.

How far in the future is Andromeda?

Sometime in the far distant future, about 4 billion years from now, our Milky Way galaxy will collide with the neighboring Andromeda galaxy, as illustrated in this artist's rendition.

Is the sun 8 minutes in the past?

The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. Not much changes about the Sun in so short a time, but it still means that when you look at the Sun, you see it as it was 8 minutes ago.

How is the universe 93 billion light years?

The scientists have estimated their current location, due to the expansion of the universe as 46.5 billion light years away, hence the diameter of the visible universe is 93 billion light years. This means that the farthest galaxies moved 30 billion light years away in 13.8 billion years.

How long would it take to travel 500 light years?

The light travels at the speed of 1 light year. Therefore, if we assume light to be travelling, then it will travel 500 light years in 500 years.

Is space infinite?

Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.

Can we see 100 billion light years away?

The light that travels the longest gets stretched by the greatest amount, and the object that emitted that light is now at a greater distance because the universe is expanding. We can see objects up to 46.1 billion light-years away precisely because of the expanding universe.

Why can't we see 15 billion light years away?

We will never see the light from objects that are currently more than 15 billion light years away, because the universe is still expanding. We are losing 20,000 stars every second to an area that will forever remain beyond our future view.

Can we travel 1 light-year?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

How long is a day in a light-year?

1 Light Year in Days

As defined by the International Astronomical units (IAU), A light year is the distance traveled by light in a vacuum in one Julian year is equal to 365.25 days. Therefore, one light - year = 365.25 days.

How long is 1 second in light years?

None. Seconds are a unit of time, a lightyear is a unit of distance. A lightyear is the distance that light travels in a year. L light year is a measure of distance not a measurement of time that relies on the constancy of the speed that light travels through free space.
